Abstract :
Cohn called a ring $R$ is reversible if whenever $ab = 0,$ then $ba = 0$ for $a,bin R.$ The reversible property is an important role in noncommutative ring theory. Recently, AbdulJabbar et al. studied the reversible ring property on nilpotent elements, introducing the concept of commutativity of nilpotent elements at zero (simply, a CNZ ring). In this paper, we extend the CNZ property of a ring as follows: Let $R$ be a ring and $alpha$ an endomorphism of $R$, we say that $ R $ is right (resp., left) $alpha$nilshifting ring if whenever $ aalpha(b) = 0 $ (resp., $alpha(a)b = 0$) for nilpotents $a,b$ in $R$, $ balpha(a) = 0 $ (resp., $ alpha(b)a= 0) $. The characterization of $alpha$nilshifting rings and their related properties are investigated.
